Fix jsweep workflow test failures and add snapshot schema support

[Copilot]

The TestJSweepWorkflowConfiguration test was failing due to missing validation phrases in the jsweep workflow. Additionally, the GitHub Actions workflow schema lacked support for the snapshot keyword.

Changes

jsweep.md workflow validation phrases

• Added "verify no type errors" and "type safety" to TypeScript validation step
• Added "ensure consistent formatting" to Prettier formatting step
• Added "verify all tests pass" to test verification step

GitHub Actions schema snapshot support

• Added snapshot definition to github-workflow.json supporting both string and object syntax:

  {
    "snapshot": "image-name"
  }
  // or
  {
    "snapshot": {
      "image-name": "custom-image",
      "version": "1.0.0"
    }
  }

• Schema files are embedded via //go:embed, requiring binary rebuild

Workflow recompilation

• Rebuilt binary to embed updated schema
• Recompiled jsweep.lock.yml with updated validation phrases

<issue_description>## Summary

This PR fixes CI test failures in the pkg/workflow package by addressing missing validation phrases in the jsweep workflow and adding GitHub Actions snapshot feature support to the workflow schema.

Changes Made

1. Fixed jsweep.md Workflow Test Requirements

The TestJSweepWorkflowConfiguration test was failing because the jsweep workflow was missing specific validation phrases. Added the following required text:

• TypeScript validation: Added "verify no type errors" and "type safety" to emphasize the importance of type checking
• Prettier formatting: Added "ensure consistent formatting" to reinforce formatting standards
• Test verification: Added "verify all tests pass" to clarify test requirements

These changes improve the workflow instructions by making validation requirements more explicit for contributors.

2. Added GitHub Actions Snapshot Support

Updated pkg/workflow/schemas/github-workflow.json to add support for the snapshot keyword in job definitions. This enables custom image generation for GitHub Actions workflows:

• Added snapshot definition with support for both string and mapping syntax
• Supports image-name and optional version properties
• Includes proper JSON schema validation for version patterns

Since schema files are embedded using //go:embed directives, rebuilt the binary to include the schema changes.

3. Recompiled All Workflows

After schema changes, recompiled all workflow lock files to ensure they use the latest schema validation. Compiled 130 workflows successfully with expected warnings about:

• Schedule fuzzy timing recommendations
• Campaign spec missing workflow files (known issue - those workflows don't exist yet)

Validation

✅ All Go tests passing:

go test -short ./...

• All packages: ✅ PASS
• pkg/workflow: ✅ PASS (was failing before)
• TestJSweepWorkflowConfiguration: ✅ PASS (was failing before)

✅ Code formatted with go fmt

✅ Workflows recompiled successfully

Notes

• Known issue: The mcp-inspector.md workflow fails compilation due to an npm environment issue (Cannot find module '../lib/cli.js'). This is a pre-existing environment problem not introduced by these changes.
• All other 129 workflows compile successfully

Subject: [PATCH] fix: update jsweep workflow test requirements and add
 snapshot support to schema

- Add required phrases to jsweep.md to satisfy test expectations
- Update schema to support GitHub Actions snapshot feature for custom images
- Recompile all workflow lock files after schema change

The jsweep workflow test was failing because it expected specific phrases:
- 'verify no type errors' and 'type safety' for TypeScript validation
- 'ensure consistent formatting' for prettier formatting
- 'verify all tests pass' for test verification

Added these phrases to the workflow instructions to ensure proper validation
guidance for contributors.

Also updated github-workflow.json schema to add snapshot support for
custom image generation in GitHub Actions workflows.
